ATTACHMENT non o'onN r'LANTERs.

Application filed neemb'er 23,- 19211. serirNo. 524,402;

of Indiana, have invented a'certainnew and useful Attachment for Corn Planters; and l do hereby declare that the following' is a full, clear, and exact description thereof, reference being .had to the accompanying drawings, in which like numerals' refer to like parts.

This invention relates to corri planters, plant setters and the like, and such vfarming implements as it may bey necessary to guide dur-ing their operation, and more particularly to the means for manipulating the marker common to such machines for causing the ground to be marked, whereby the planted rows will be properly spaced.

On machinesv of this type it is a common practice to provide a laterally extending shaft having a disk marker on the end thereof which rides upon the groundat aset distance from the machine for marking ythe saine and thereby giving. .the opera-tor a line for guidance upon the return trip' across the field.- It is, therefore, necessary upon making each turn that the marker be moved from one side of the machine to theother, andy also elevated until after the machine is turned. There have `beeny types of' machines having automatically operated markers, but the majority of such machines depend upon the operator reaching down a considerable distance below the seat and behind the same, grasping the shaft and elevating the disk so as to hold it from the grounduntil the machine is turned and then dropping it on the other side. This is diflicult to do While turning, because of the handling of the team and the planting mechanism of the machine during the turning movement.

It is the object of this invention to pro vide a simple arrangement for permitting the marker to be elevated and dropped on the other side of the machine while turning,

by means of a conveniently positioned hand n lever which may be readily grasped and quickly operated by the driver.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim.

In the drawings, Fig. 1 is a plan view of a corn planter showing the marker operating attachment with the marker in ground enchine, as indicated in. Fig.` 1.

gaging position. Fig. 2 is ,a side elevation l of the same showing the marker in Velevated position.

In the drawings thereis shown acorn planter having the usual framel 10, axle 11 'and wheels 12, the frame being'attached-to a forward. cross bar 13 to which is connected theL pole 14, and braces. 15. Supportedupon the cross bar 13, there are corn hoppers 16 .provided withv thev usual cuttersor` openers 17 which open the earth and .permit the seed.r

to drop therein from the hopper. The hopper is' provided with valves for controlling the discharge-.of the seed therefrom,l not .shown herein, drivenby the usual shaft y18,

4is supportedv in elevated position on the frame 10 by the supporting members 23 andv` 2171.- The `above described construction yis of the common and well-` knowntype, and

there-is shown andv described' herein; only `the skeleton parts of the machine necessary for its operation? omitting the detailsof the y adjusting and controlling mechanism for the planters. l

The marker comprises a shaft 25- pivotall-y secured at its end upon the rea-r of the frame 10v andso bent'as to clear thewheels 12 and seat 22. It extends laterally from the ma- On-,the end of tlhel shaft 25,v there is a marker disk 26' adapted to ride upon the ground for marking the same, said disk being mounted upon a bar 27 which is slidably adjustable in the shaft 25 for permitting the device to make a mark at the desired distance from the wheels. Pivotally mounted upon one of the side bars yof the frame 10 and immediately forward of the seat 22, there is a hand lever 28 provided with the latch 29 and latching rod 8O on the end of which there is the usual pawl 31 engaging in the ratchet 32. Attached to said lever intermediate its ends, there is a cable 33 which passes about a pulley 34 mounted upon said frame forward of said lever, and thence about the drum 35 mounted at the rear of the lever. The drum 35 is keyed upon the shaft 86 which is mounted in suitable bearings between the side bars of the frame 10 so as to cause said shaft to turn with the movement of the lever 28. Keyed centrally of said shaft and immediately below the seat 22, there is a drum 37 of in.

creased diameter about which -there is wound vthe cable 38 which extends upwardly over the pulley 39, which is mounted in a de-k pending bracket 41-.0 secured ,to the bottoni of the seat 22. The'cable 38 passes from .over the pulle 3,9 horizontally under saidv seat between t e pulleys Hand 42 which are mounted upon thebracket 43 extending. rearwardly from the bottom of the seat 22 to a position substantially in the plane 'of the laterally extendingshaft 25. Said pulleys are Grooved so that the cable 38 cannot "escape #from y between them. Said cable -passes about one of said pulleys and lis vat- ',tac'hed at its end toa ring 44; mounted upon said shaft. I' 1 f y By means of this arrangementwhen a turn is .madev and the corn planter'y is driven inthe opposite] direction,- the operator who vis vseated upon vthe seat 22 grasps vthe hand lever 28 vand vpullsjit back smartly causing v .thecable 33 to turn the 'shaft 36upon'fwhich keyed the drum 37,*said drum pulling'in on the cable 38 so asv to'elevate the lshaft 25 to 'asubstantially perpendicular position Vas "shown 'in` Fig. y2. f As the shaft 25 andv [marken-26 are brought upwardly bythe 44movement offfsaid lever, they continue to `move over dead center and lean -slightlyin the opposite direction; With themarkerso elevated, the ylever 'is released and remains its vupright' position, asv shown Fi'g52, until'- the corn' planter has been turned and it` is desired toi lower thel inarke'r.' Thev op erator then releases the latch '29 pushing the lever forward, which permits the marker to be lowered vinto groundengaging position'. Since the sharp upward movement of Y'the marker has caused it to"pass"over` dead 4center and' incline `toward the opposite side i ofthe planter 'from which it had rbeen-riding, when" it is`. released it falls upon the opposite side asgdesired and 'is then readyvf `reves, .in the 0psameprinci1f lemay be "eniploiyedwvith the useof foot levers or chains,=sprockets"and t this invention.V
